True, very true. As models get deprecated they stop releasing firmware. However they do release firmware at least once a year for all current models. However the Billion is tough as nails, I've had one sitting in a warehouse for 8 years without even flinching.
Sadly they're expensive, but for good reason. The built in firewall is very good and LAN transfer at full Gigabit speeds.
The Cisco 800 series ISR is even better, but at ~R7+k for a router without WiFi it's not really aimed at the home user.
